You would take the amount of increase and divide it by the amount of total cost over the time period of certain months. Then you would multiply that number by the percentage of increase gained, and subtract 96.12 to get your answer.

Answer:

-63

Step-by-step explanation:

5×9 = 45

45/-5 = -9

-9×7 = -63

Answer:

Explanation:

1.

n²-49=0

n=√49

n=7

2.

x²+64=0

x=√64

x=8

3.

if A=144x²

l = √A

l = √(144x²)

l = 12x

4.

b = (24×2)/3b

b = 48/3b

b = 16/b

b² = 16

b = √16

b = 4 in (-4 is correct in algebra but there's no negative lengths in geometric shapes)

5.

x²+z = 103

x² = 103-z

x = √(103-z)

for x = -9 and 9    (103-z) must equal 81

z = 103 - 81 = 22

x = √(103-22)

x = √81

x = -9 , 9

Answer:

m = 5

Step-by-step explanation:

(5,-2) and (9,18)

Slope:

m=(y2-y1)/(x2-x1)

m=(18+2)/(9-5)

m=20/4

m = 5

Answer:

24

Step-by-step explanation:

Equation: x + 11 = 35

1. Subtract 11 from both sides

x + 11 = 35

  -11      -11

x = 24

Answer:

x is 24

Step-by-step explanation:

Let's write it down as an equation

If number x is increased by 11, we'll write is as x+11 and the result of that is 35, so x + 11 = 35

x + 11 = 35 implies that

x = 35 - 11

35 - 11 = 24

x = 24

Answer: The figure is a rectangular pyramid. It has 5 faces, 4 edges, & 5 vertices.

Hope it helps.

The net can be folded into a rectangular pyramid with 4 edges, 5 faces, and 5 vertices.

Pyramids are three-dimensional structures having triangle faces and have an encompassing polygon shape at its base. If the base of a pyramid is rectangular, then it is called a rectangular pyramid.

If we join the open ends of the triangles on top, we will get a rectangular pyramid.

Answer:

x = 30

Step-by-step explanation:

[tex] \triangle JLK\sim\triangle PQR[/tex] (given)

[tex] \therefore \frac{JL}{PQ}=\frac{LK}{QR} [/tex]

(corresponding sides of similar triangles)

[tex] \therefore \frac{20}{x}=\frac{22}{33} [/tex]

[tex] \therefore \frac{20}{x}=\frac{2}{3} [/tex]

[tex] \therefore x=\frac{20\times 3}{2} [/tex]

[tex] \therefore x=\frac{60}{2} [/tex]

[tex] \therefore x=30 [/tex]

Or using scale factor:

Scale factor = 33/22 = 3/2

x = 20*3/2

x = 10*3

x = 30

Answer:

E) 5.4m

Step-by-step explanation:

ratio of triangle FGH : triangle JKL => 2.1 : 1.4

perimeter of triangle FGH = x

2.1 : 1.4 = x : 3.6

=> 1.4x = 2.1 × 3.6

=> x = 2.1 × 3.6 ÷ 1.4 = 5.4

Answer:

you will pay $60

Step-by-step explanation:

25% (1/4) of 80 is 20

subtract 20 from the total (80)

80 - 20 = 60

$60

Answer:

60

Step-by-step explanation:

So if you get 25% off, you're basically paying 75%.

So first, convert the percentage to a decimal:

75% = 75/100 = 0.75

Now just multiply the decimal by the total cost:

80$ (0.75) = $60

Answer:

20 units

Step-by-step explanation:

Volume of a cylinder = πr²h

V = πr²h

height, h = 7

V = π * r² * 7

V = 8792

8792 = 21.991148 * r²

r² = 8792 / 21.991148

r² = 399.79722

r = √399.79722

r = 19.99unit

r = 20 units

Answer:

D

Step-by-step explanation:

The answer is D. 6 is the whole number with no decimal after it so it goes before the decimal. Then we add the numbers after the decimal. 0.2 is the same as 0.20 so we add 0.20 plus 0.09 which gets us 0.29. Lastly, we add this all together and get a total of 6.29. Hope this helps!

How the sales tax de-calculator works

Step 1: take the total price and divide it by one plus the tax rate.

Step 2: multiply the result from step one by the tax rate to get the dollars of tax.

Step 3: subtract the dollars of tax from step 2 from the total price.

Pre-Tax Price = TP – [(TP / (1 + r) x r]

TP = Total Price.
